## The Hook

Rive Wasm runtime plays state-machine animations when Lottie is too linear.

## What's Good

MIT runtime. State machines, low-overhead Wasm, React/Flutter/web bindings.

## The Catch

Authoring lives in Rive editor freemium seats. Not After Effects Lottie. Distinct from lottie-web and Theatre.js timeline studio.

## Verdict

MIT runtime plus freemium editor. Runtime free.
